> At absolute best, SMR disks underperform significantly in comparison to CMR disks; at their worst, they can fall flat on their face so badly that they may be mistakenly detected as failed hardware.
> Although obviously slower than their Ironwolf competitors, they performed adequately both for conventional RAID rebuilds and for typical day-to-day NAS file-sharing workloads.
> Even in the best case, the SMR models of WD Red underperform their earlier, non-SMR counterparts substantially—and consumers were not given clear notice of the downgrade.
> Unfortunately, Western Digital has so far only chosen to use it to cut manufacturing costs on small disks, without even passing the savings along to the consumer.

Taky tam zreprodukovali ten ServeTheHome test, kde byl v nejhorším případě SMR Red 16x pomalejší než IronWolf.
